Ordinal Pay-offs Ordinal payoffs are numbers representing the
outcomes of a game where the value of the numbers is not important,
but only the ordering of numbers. i.e. 1. best =0 2.Second best=3
3.Third best=6 4.Worst =X

Case 1 If they both cooperate, the lack of testimony from the
two prisoners weakens the case. There is still enough
circumstantial evidence, however, to keep them in prison for two
years each (payoff of 3 years off from the base sentence of five).
(reward
Slide 17
Case II If they both defect, the testimony that each provides
against the other is quite damning. But their slightly conflicting
stories allows the judge to imprison them for only four years each
(payoff of 1 year off from the base sentence of five).
(punishment
Slide 18
Case III If one player defects and the other cooperates then
there is no case against the defector, but a very strong one
against the cooperator. The defector gets immunity and receives no
prison sentence (payoff of 5 years off from the base sentence of
five), while the judge throws the book at the cooperator who gets
the full five year sentence (payoff of 0 years off from the base
sentence of five). (sucker's payoff)
